REGISTERING LOCK.

.Q'PECXFICATION forming part of Letters Patent No. 452,438, dated May19, 1891. Application filed September 2, 1890. Serial No. 363,786. (Nomodel.)

To @ZZ whom it may concern: Y

Be it known that I, WILLIAM F. BEAsLEY, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Registering Iiocks; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

My invention consists in certain improvements in locks, and it moreespecially Vrelates to the same class thereof as that to which thepatent, No, 220,124.granted September 30, 1879, to Henry Clarke,`belongs, upon which patent my present invention is an improvement,consisting in the following features designed to accomplish thehereinafter-mentioned objects. In order vto prevent the lateral bendingof the shackle of the lock, (which has heretofore been made of brass, asthat has been found most advantageous on account of the facility withwhich it may be worked,) I cast the metal forming the outside thereofaround a central core of steel, which is elliptical in cross-section,the major axis of the ellipse being vertical. This core, which I bypreference secure in place by lugs upon its sides', may be formed ofhard steel, so that upon a bending of the shackle it will be broken,preventing a concealment of the injury, such as would be attempted byany one tampering with the lock who would desire to conceal his attempt,and it will be seen that the core will strengthen the hasp not onlyagainst lateral bending, but against an attempt to straighten it. I mayalso form perforations extending through the said outer casing and core,the said perforations being normally in line with each other; and it isobvious that if a hasp having these perforations is bent, on account ofthe compression of the outer casing upon one side andthe expansion uponthe other, the perforations will no longer register, nor will there ifthe hasp be'bent in the opposite direction, thus straightening it, asthe outer easing will slide upon the met-al of the core, leaving a readymeans of ascertaining whether the hasp has been subjected to violence.In order to prevent the backward movement of the barrel carrying theshackle, which in this class of locks is objectionable, as it rendersthe register thereof useless, and in order to relieve the locking-pinsproper of the barrel from strains attending resistance to such backwardmotion, I provide an independent pin engaging shoulders arranged uponthe barrel at different points on the circumference thereof, one of thesaid shoulders on the barrel being so situated as to be engaged by thesaid pin upon the locking-pins dropping in their holes in the barrel. Itwill thus be noticed that much of the strain that has heretofore beenborne by the locking-pins is now carried by the independent pin, which,as it does not enter any holes, may be made much heavier than thelocking-pins and may be slightly bent without impairing its efficiency.

.My invention also consists in the construction, arrangement, andcombination of the parts of which it is composed, as will be hereinaftermore fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts aredesignated by similar letters, Figure l is a side View of a lockconstructed in accordance with my invention, the casing thereof beingremoved and the shackle being in section and being also shown in dottedlines in a locked position. Fig. 2 is a section on line X X of Fig.

l. Fig. o is a section on line X X of Fig. l.

The barrel A is constructed in the manner as described in the saidpatent to Clarke and carries the indicating-wheels B thereon in themanner made known thereby, the post A', mounted on t-he top plate A2,carrying the train-Wheels B', which are also shown therein and now needno furtherdescription. The curved elliptical steel piece C (the majoraxis of which is vertical) is contained Within the shackle D, which isformed upon the upper end of the barrel A, it being secured therein vbylugs c upon its sides, which are held by the outer brass coating C ofthe shackle which is cast around the core C, the perforat-ions c passingthrough 'the core C and outer coating C', as is seen in Fig. 5. If theshackle be bent in the direction indicated by the arrows andsubsequently straightened, it will be found that the holes no longerreg- IOO ister, but have the relative position shown in dotted lilies inFig. 5, thnsall'ording a means ot detecting whether the lock has beentampered with. It will also be seen that it the steel is hard it willbreak if bent, thus giving additional evidence and at the same timeStreu gthenin g the shackle against bending.

The projection E upon the top of the top plate A2 has a shoulder e uponthe outer end of its top, the inner face of the said shoulder beinginclined and overhung, as at e', while the lower surface of the free endel' the shackle has a shoulder cL2 upon its inner end, the outer face etthe shoulder c2 being inclined to correspond with the inner face of theshoulder e. It will thus be seen that the said shoulders being engaged,as shown in dotted lines in Fig. l, it will be exceedingly diiicult tolift the end of the shackle in the direction indicated by the arrow inthe said ligure, which would straighten it..

The collar F, secured to the barrel A, has a series of shoulders F F2Fgin the upper end thereof, the said shoulders being on thecircumference of a circle taken at right angles to the axis of thebarrel, while a shoulder F1 extends entirely across the collar in therear ot the shoulder F and the locking-holes f, the two latter beingaligned, as seen in Fig. l, while a depression 7 is cut in the collarslightly in advance of the shoulder F', the said shoulders having rearsquare faces and inclined forward ones, the reverse being true of thedepression.

In addition to the usual locking-pins f", which enter the locking-holesf, I provide an extra pin f2, (preferably of a greatersize than it isusual to make thelocking-pins,) which is housed in the aperture f3 inthe housings f1 on the base of the top plate A2 and in the same plane asthe shoulders F F2 Fis and depression f', with which the said pin istherefore adapted to engage. As the pin is aligned with thelocking-pins, it will be seen that it will engage the rear squareface ofthe shoulder F when the locking-pins enter the holes .|f, thus relievingthe locking-pins against any backward strain that may be exerted uponthe shackle whilein a locked position, the pin f2 being held against thebottom of theshonlder by means of the usual spring ff. It the key be nowinserted, the locking-pins will be forced outward, liberating thebarrel, which may then be turned slightly in a forward direction (i. e.,that of the arrow in Fig. 2) until the locking-pins fall behind theshoulder Ft, again locking the barrel against backward rotation, the endot the shackle then having the position y. It the rotationbe continued,the pinf'? will engage the shoulder F9, or, 1f Vfurther continued, theshoulder F, the end of the shackle then bein g fy and y2, respectively.The rotation may be still further continued until the pin f2 engages thedepression f', again locking the barrel against backward rotation, theend of the shackle being now at g/f". It the movement be still furthercontinued, the locking-pins will fall into the holes f, while the pin f2will engage the shoulder F', as has been described, the end of theshackle being now at y". I by preference so arrange the registeringmechanism that the wheels will be actuated by the movement of the end onthe shackle between i/1 and y, the latter point being at such a distancefrom the projection E that it will be impossible to release the haspheld within the shackle until the rotation has been registered. It willbe seen that by this construction the locking pins are relieved from allstrain against backward rotation,except in position fy, while theregistering wheels are entirely relieved from strain.

Having thus described my invention, what l claim is- 1. A shacklecomposed of flexible material having a central core of brittle materialtherein, as described.

2. A shackle of flexible material having a central core ot brittlematerial therein, the said core having lugs upon its sides, asdescribed.

S. A shackle consisting of an outer casing and a central brittle coreand having perforations extending through the said parts, as described.

l. A shackle consisting of an outer flexible casing and a centralbrittle core of elliptical cross-section having lugs upon its sides, thesaid core and a casing having perforations extending therethrough, asdescribed.

5. In a lock, the combination of a barrel having a collar thereon, thesaid collar having a shoulder extending across its surface and a seriesof independent shoulders upon its upper end extending around itsperiphery, pins locking the said barrel in position, and an independentpin engaging the said independent shoulders upon the collar, asdescribed.

In testimony whereof I atlix my signature in presence of two witnesses.
